“…Many different types of slow pyrolysis reactors have been developed (Demirbas et al 2016;Kan et al 2016). Charcoal is used for the production of activated carbon, e.g., as a feed additive, in medicine, as a basis for catalysts, and for gas and water cleaning.…”

“…Generally, a charcoal producer requires about 4-5 t of dry wood to produce 1 t of charcoal depending on certain factors explained above (Demirbas et al 2016;Demirbas 2009). This translates to 20% of usable charcoal with 80% of the dry wood being wasted in the production process.…”

“…Sustainable charcoal production aims at minimizing material and energy losses at all stages of production is a critical essence (Demirbas et al 2016). Management and efficient utilization of the wood sources is still a critical issue for sustainable and clean charcoal production in the midst of increasing charcoal demand in the urban areas.…”

“…This has reduced the many challenges in industry to a debate of actual magnitude of charcoal produced, quantity of consumed and impacts of production on forest and woodland or livelihoods of both rural and urban poor (idem.). This debate has gone on for some time to the detriment of reduction of waste associated with charcoal production as expected in sustainable and clean charcoal production (Demirbas et al 2016). Though the amount of waste associated with the charcoal value chain has not been estimated, reduction of wood and charcoal wastes can reduce pressure on the sources of wood for charcoal production and ensure sustainable charcoal production and use.…”

Carbonization and pyrolysis; Charcoal and biochar Definitions Charcoal is a solid biofuel produced from biomass through a process of carbonization. Carbonization is the process of thermal decomposition of biomass under conditions of limited or no oxygen. Efficiency of charcoal production is the adoption of practices that improve wood-to-charcoal conversion rates and yield preferred socio-ecological outcomes.

“…The slow pyrolysis of wood generally yields 35% of char, 30% of crude PA, and 35% of non-condensable gas, 6 which greatly depends on the wood parameters (such as species, size, and humidity), pyrolysis system, processing time, and final temperature. 7 The main proportion of PA is water (80-90%) and the rest consists of organic compounds comprising organic acids, alkane, phenolic, alcohol, and ester. 3,4 It was reported that the crude PA yield from sawdust of Chinese fir increased with an increase in pyrolysis temperature from 250 to 550 °C.…”

The use of pyrolysis acid (PA) as a liquid by‐product of the slow pyrolysis of wood or any other lignocellulosic biomass has been widely developed in agriculture for a variety of purposes such as crop enhancement or as a pesticide. Evidence from the literature suggests that PA could be used as a sustainable wood preservative to protect against rot fungi and termites. The experimental work presented here provides one of the first investigations into the anti‐decay efficiency of PA. Crude PA acid acquired from three different types of wood at two different temperature ranges (180–280 °C and 280–350 °C) was used to impregnate beech and pine wood samples in a full‐cell process. Then, the resistance of treated samples against white and brown rot fungi was evaluated (in accordance with European standard EN 113), before and after a leaching test (European standard EN 84). It was found that, generally, higher retention of chemicals inside the wood was observed with PA obtained at 350 °C (PA‐350). The leaching rate of chemicals from the treated samples with PA obtained at 280 °C (PA‐280) was significantly higher than from those treated with PA‐350. Before leaching, no statistical difference was observed among the impregnated woods in terms of decay resistance. Although the samples treated with PA‐280 initially showed fairly good decay resistance they partially lost it after leaching. This was particularly the case with brown rot. However, the impregnation of wood samples with PA‐350 met the requirements of EN 113 as an efficient treatment against basidiomycete fungi. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd
